As I mentioned before I am 60 and I started my higher education journey five years ago, after spending a life time in practical design and manufacture. One year open university maths and four years of full time EEE course. I am having my last exam on Friday in wireless communications. Then I have to do my presentation for my project/dissertation. Then freedom.
I would not like to sound like one of those who thinks knows better, and tells everybody how things should be, but I think exam is an outdated concept. (I have also heard that from a few high calibre academics.) As I mentioned before we had a guy in year three who did not know the difference between AC and DC. But passed the exam. One may say that is an exception, but not really. So, clearly exams are not a reliable (or fair) metrics to measure one's learning or success.
I also do not believe that teaching by humiliation produces better results. There are ways to get student engaged and that does not require trophy by only participating either.
In this modern day with the amount of material available on the internet the universities should re-evaluate their role. There is no under graduate theory (again in EEE) they teach that can not be learned on the internet. In fact, any of my classmates that I am in contact with have always been on the internet to supplement their learning after lectures. And they still have not acquired the electrical fundamentals.
Four years of study, one can still not design a sh*t, but thanks god we did all that laplace and fourier and can write beautiful equations even though we do not know what the hell they mean.
So, clearly something wrong here.
Electronics, as a subject is not what it used to be, say when I started learning in mid '70s. It is vastly wider. So, instead of trying to cram bits of everything, which results in producing jack of all trades and master of none, focus on the things that matters.
Now, you made a point in differentiating between an EE and a lab technician. I argue that you do not even realise that, what is coming out of the universities are actually not engineers but glorified technicians. If one is going to learn how to design in the industry, what is the role of a university education, as one can also learn the theory in the industry (or internet). So, a good re-think is way overdue I think.
What made you go into teaching?
Sahib, I realize that things are not perfect, I do believe that exams or tests are the correct way to evaluate in most cases, however, the problem is the approach they give to tests, if the tests are just about memorizing what the teacher said and then writting it on paper so it proves that you remember it then its worthless... An engineering test should be a problem in which you apply your knowledge, problems should not be variations of what you already learned during lectures, they should be related to what you learned but different by making you think instead of mere repetition or application of an algorithm.
I don't think humiliation is the way to go either, but it proves that the opposite is worse, namely being extremely agreeable, permissive and kind.
Engineers are NOT glorified technicians, a technician wont go beyond, he may become a better technician or more specialized but he will remain a technician. What you are failing to see is that a BS does not mean you are suddenly ready for everything, that is why there are Master and PhD degrees. A Bs should give you the foundations of the discipline you selected, it should give you a broad spectrum, that is why EEs also need to know mechanics, thermodynamics, etc... you are studying an engineering degree which is oriented to a certain area but that doesn't make you a specialist in that area. An engineer with Bs can then go into different fields like administration by studying an MA, or into physics, math, finance and so on, a technician can't.
To give you an example, I am about to study an online master's degree in catholic theology, and I am an EE!, they require that you have an undergrad degree, as an EE I can apply to that degree, as a technician I cant.
Its very different to how things were before, decades ago, electronics wasn't such a vast field, so if you studied a Bs in EE you didn't have to cram in so many different subjects in a 4 year program, if the only thing available back then was vacuum tubes and analog, then you could study many subjects on analog electronics, and so on, now you have power electronics, analog electronics, digital electronics, signal processing, communications, power systems, automation, software, computer networks, control, etc.. etc.. so universities have to incorporate all of that in a 4 year program, that obviously means that you wont be that specialized after you finish. But that is the point, nowadays a Bs is meant to be the foundation, then you can become an expert in a certain field by going through a master or phd degree.... a Bs in EE today is much different than an Bs. in EE 50 years ago.
I do agree that most BsEEs fresh out of college get a glorified technician job, for the same reasons I explained above.
You can learn most of a Bs education online, but a masters and a PhD are a completely different thing, to begin with there is the issue of the equipment used, you might make it with a cheap scope and a DMM in your undergrad years, but in a master or phd you will probably need specialized labs with millions of dollars worth of equipment, also, what you learn under an advisor or researcher from a specific topic is not available on Khan academy. There is also the issue that you need access and read a lot of what is called "the state of the art" which are basically peer reviewed research papers on a specific subject, and know what exactly is being done today in terms of your research field, specially if you are doing a PhD, so you need access to the most relevant journals, most universities have free access to these journals, otherwise you would have to pay a lot for memberships. And then of course its the matter of accreditation, if you want a masters or PhD you need that little paper which says that you are a Bs in EE.
Also, most design jobs in big name companies require at least a masters preferably a PhD.
You can become a Bs. and go into the industry and learn from a mentor from a specific field, that is also very similar to the academic process I described.
Why did I go into education? several reasons, I am an academic, I like the academic side of engineering, I believe I like more the process of studying, reading and learning rather than making or building stuff if that makes any sense, I enjoy making curcuits but I am more an armchair engineer if you like.... I do not enjoy that much working in a traditional office/factory/building, etc.... Also, as you said, much of the theory you learn in a Bs is not used practically in most everyday jobs, and I love that theory, so teaching gives me the opportunity to use that theory and learn more about it by teaching. I was offered a teaching job in 2013 teaching electronics in an audio school, and I've been doing it ever since, in 2016 after I finished my masters I was offered another job teaching analog electronics at a major university and I have also been teaching there since.
